The power loss (2-3 hp) due to the slight increase in exhaust backpressure is a fraction of the parasitic loss of a supercharger. In some cases the sound attenuation from the turbo is enough that mufflers are'nt required negating the loss from the turbo. Just some trivial I picked up with my mech eng degree.

 

Thats funny... Actually it does come out of hot air

 

A maxed out LS7 can and has done 600rwhp. The best you can hope for on a S/C system in mid 600's and I dont care who is running 700 on borrowed time with a stock botom end. S/C power is not comparable with N/A for power under the curve.

I would cam the LS7 and never look back. Later it will be able to support FI; best of both worlds.

 

That is a sick sounding car. Way too much power for the street though. 20k price tag is bit pricey also but for some well worth it.

 

Yep...just BS. Nothing and I mean nothing does not have some parasitic loss. I am always amazed at what I see on the Internet!

 

No offence but where did you get a mechanical engineering degree that taught you turbos have no parasitic loss.....Wal Mart?

 

It was from reading all the rantings of this man that made me decide to stay NA. So if my car is slow, I'm blaming him.

Hahaha...hey now that's not nice. I am stopping by there later tonight though, so I may just pick one up if they have them.

 

***** you!!
What makes a "Compliance Office” technically qualified to do other than pick his nose? What courses in turbo machinery did you take? How many decade of experience designing turbo facilities do you have? If the answer to either question is none shut your hole. Don’t assume your wasting time on a car forum gives you any kind of technically qualification.

 

Thank you for your input

 

You're really getting quite picky if you are saying a turbo setup is a "parasitic loss". Turbochargers are very close to "free" power as they utilize usually wasted exhaust gas to spool up the snail and can be very efficient. You can start calculating how much speed is lost due to wheel weights slowing down initial accelleration due to inertia. Don't forget to shave before you head down the 1/4 mile as this could also be significant. In short, a properly designed turbo system more than makes up for any tiny "parasitic loss" measurable. Superchargers and turbochargers both have their advantages. To each his own.
I personally find the Corvette to be a bit FI "unfriendly" for several reasons. There isn't a lot of room under the hood, and it's hot under the hood already. Superchargers add weight to the front of the car, or top of the car. I'd prefer my weight to be lower and more towards the rear of the car. The APS kit has the turbos low, but it exposes all the hardware to the elements, which I see as a problem if not shielded and/or wrapped.
I'm a big fan of FI, I just am not convinced that the stock Corvette is the best candidate for FI. I think bolt-ons may be a better way to go if open-tracking the car to preclude heat-soak scenarios. Just my opinion and this is my first Corvette. I tend to read everything I can and try to sort through "wheat and chaffe".

Dealers in Detroit are advertising $6K off of list for Z06's, so why not just sell what you have a buy a Z06 and move on. Unless you plan to keep the car forever, you will never get your money back and may actual hurt the value.

Just my opinion.
